Parker PGP050 PGP051 pumps are fixed / positive displacement gear pumps. They offer high durability and resistance to oil contamination due to their cast iron, roller bearing construction. They are available as single or multi-section pumps with an integral valve. Single pumps are coded ‘A’ or tandem pumps are coded ‘B’.
Manufactured with hi-tensile grey iron, these pumps have a wide variety of drive shafts designed for high-torque applications; unique pressure-balanced thrust plates contribute to optimised performance.
Other features and benefits include:
- Three-piece cast iron construction for distribution flexibility and durability
- Balanced thrust plates minimise friction and leakage
- Roller bearings for durability
- Multiple sections available
